Burning Spirit Wood
"Here's the Thunder God Vine. Please check it to see if there are any problems." The store worker opened the box, revealing a single strand of purple vine that has what appears to be lightning lines going through it.
Su Yang looked at the Thunder God Vine for a moment before nodding his head, "It looks right."
"Then that will be 100,000 high-grade spirit stones."
Luo Ziyi then placed 10 flawless-quality spirit stones that were worth 100,000 high-grade spirit stones on the desk.
The worker accepted the money before wrapping the box in front of them and handing it over.
"Thank you for your business," he said to them.
Su Yang immediately tossed the treasure inside his storage ring before leaving the place.
"How many more do we need?" Luo Ziyi asked him afterward.
"8 more ingredients," he said.
After their first successful trip, the two of them proceeded to visit every single medicine store within the Grand Celestial Plaza.
